Abstract

Drug Targeting: Drug efficacy depends on the extent of binding to a cellular target (often a protein) with adverse effects caused by excessive target binding or by off-target binding. Engagement of a target protein inside cells is influenced by the effective drug concentration and by factors that regulate the protein conformation, making it difficult to predict efficacy based on in vitro affinity studies. Martinez Molina et al. (p. 84 ) took advantage of the shift in protein thermal stability caused by drug binding to directly monitor target protein-drug interactions in cells. The method was used to monitor drug target engagement in cancer cells and in mouse livers and kidneys.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
